VAPOR-BURNER STOVE.

SPECIFICATION forming part of Letters Patent No. 323,120, dated July 28, 1885.

Application tiled December 13, 1884. (No model.)

T 0 all whom it may concern.-

Be it known that I, ZEBULON DAVIS, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Vapor-Burner Stoves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as-will enable others skilled in the art to which it pertains to make and use it, reference beinghad to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in' vapor-burner stoves; andit consistsin the combination of a central generating-burner with a conducting-pipe for the vapor, which is provided with a burner at each end, and which has an inlet at or near its center, and which extends at an angle to the direction of the pipe, a needle-valve for controlling the flow of vapor into this pipe, and suitable dampers or valves, by means of which the vapor can be cut off from either one of the burners, as will be more fully described hereinafter.

The object of my invention is to supply two or more burners with vapor from a single point, and then regulate the flow of vapor in either direction by means of suitable dampers or cutoffs, which are placed either in the pipes or in the burners, as may be preferred.

Figure 1 is a side elevation of avapor-burner stove embodying my invention. Fig. 2 is an enlarged detail view showing the relative arrangement of the dampers to the opening. Figs. 3 and 4 are detail views of the damper. Fig. 5 is a vertical section of a burner, showing the damper located in the burner in contradistinction to the pipe. Figs. 6 and 7 are detail views of the damper. Fig. 8 is a perspective of the burners and their attachments complete. Fig. 9 is an enlarged detail view of one of the valves or cut-offs.

A represents the stand-pipe; B, the central generating-burner; O, the generating tube or chamber, which extends around the burner midway between its openings; D, the vaporpipe; E, the needle-valve which controls the flow of the vapor to the central burner, B; and F, the needle-valve which is placed upon the lower end of the vapor-pipe D, and which controls the flow of vapor to the end burners placed upon the pipe G.

All of the above-described parts are fully shown in an application, Serial No. 150,260, filed by me on the 13th of December, 1884, and need not, therefore, be more fully described here. In the said application two needlevalves, F, are used, where only one is used in this instance. The conductingpipe G, having a suitable vapor-burner, H, upon each of its ends, is made in one continuous piece, and has an opening or inlet for the gas at any suitable point between the two burners, but preferably midway between them. This opening extends outwardly at an angle to the length of the pipe, as shown in Fig. 2, so that the vapor can be readily projected into the pipe from the needle-valve F. The pipe G extends away upon each side of this opening, and as the vapor'passes into the opening and strikes against the back J in the pipe it spreads equally in both directions and flows freely through the pipe G toward the two burners. The back J of the pipe is preferably set in or thickened, as shown in Fig. 2, for the purpose of preventing the vapor from coming in contact with the rear side of the pipe, and thus reducing the amount of friction upon the vapor. At

., suitable distances upon each side of the opening I is made a cut or opening, L, which is preferably \l-shaped, so that the valve or damper N can move more freely, and will form a tight joint when in place. This damper N consists of a plate which has a suitable'o'pening, 0, through it, of the same size as the inner diameter of the pipe G, and is provided at one end with the slotted ear or projection P, and at the other end with a suitable handle, Q. On the pipe is formed a pro jection or ear, It, and extending outward from one side of this projection is a suitable pivot or pin, S, which passes through the ear 1?, and which serves to guide the valve or damper in its sliding movement back and forth through the cut or slot L in the pipe. \Vhen the valve is moved endwise, as shown in Fig. 1, so that its opening 0 is made to register with the pipe G, the vapor passes freely through to the burner H upon that end of the pipe. hen, however,the damper is drawn endwise, the solid portion N of the damper closes the pipe G, and then all of the vapor from the needlevalve F passes through the pipe S to the other burner. When the damper N is moved so as to only partially close the pipe, the flames of the burner can be turned down to any desired extent. By thus locating the two dampers N upon opposite sides of the opening I it will readily be seen that but a single pipe, G, and a single needle-valve, F, are needed, thus simplifying and cheapening the construction of the stove. It is not absolutely necessary that the dampers N should be placed in the pipes G, for they may be located directly in the burner, as shown in Fig. 5. In this case a perforated disk, T, is placed in the bottom of the burner upon the central bolt, U, and then a valve or damper formed from a similar perforated disk, V, is placed upon the bolt just over it, the holes in the two plates being made to register with each other when the damper is open, but to shut off the flow of vapor when the damper is closed. The damper V has a suitable handle, WV, formed upon one side, and this handle extends outward from the burner so as to be readily operated by hand. When the valve or damper is moved but a slight distance, the volume of gas to the burner is reduced so as to lessen the flames to any desired degree, and when turned so that the holes in the damper and the disk T no longer register the flame will be shut off entirely. When the vapor is thus shut off from the burner H, all the vapor then flows through the other end of the pipe G to the other burner. Two forms ofdampers or valves are here shown; but it is evident that plug-valves or any other form of devices may be used for the purpose of controlling the flow of vapor through the pipe G, as fancy may dictate. The two forms here shown answer the purpose intended very fully, and are simple and cheap; but I do not confine my invention to this peculiar construction.

Having thus described my invention, I claim 1. In a vapor-burner stove, the combination of a central generating-burner, a support therefor, and a pipe, D, for conducting away the vapor, the pipe G, having burners placed upon opposite ends, and having a central inlet for the vapor, a needle-valve placed beyond the inlet for controlling the flow of vapor to the pipe G, and valves placed in the pipe G on each side of the inlet, for controlling the flow of vapor to the burners, whereby the vapor may be divided between the two burners, or forced to one only, substantially as shown.

2. In a vapor-burner stove, the combination of a central generating-burner, the needlevalve F, the pipe G, for conduetingthe vapor to the burners, and which is provided with an inlet for the vapor, and the dampers, the dampers being adapted to open and close the pipe upon either side of the inlet-opening, substantially as described.

3. In a vapor-burner stove, the combination of a central generatingburner, the needlevalve F, the pipe G, having inlet I, and provided with cuts or slotsthrough its side, and the dampers N, provided with solid portions for closing the pipes, and the openings 0, for registering with the pipe, substantially as set forth.

4. The combination of the pipe G, having suitable slots or cuts through its side, and provided with the ear or projection R, with the damper N, having a solid portion to close the pipe, and the opening 0, for registering with the pipe, and having the slotted ear 1?, for catching over the pin S, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

ZEBULON DAVIS.
